On the machine where Agent is installed, replace logging.dll libraries with custom libraries containing a fix:

When using these custom dll files, logs will not be created by Managed Machine Service, Acronis Management Server, Acronis Storage Node.

1) Download logging.zip

2) Stop all Acronis services

3) In the following folders, rename logging.dll to logging.dll.old

  • C:\Program Files (x86)\Common Files\Acronis\BackupAndRecovery\Common
  • C:\Program Files (x86)\Common Files\Acronis\BackupAndRecovery\Common64

4) Copy the .dll files from the archive:

Place logging.dll from vs folder to C:\Program Files (x86)\Common Files\Acronis\BackupAndRecovery\Common

Place logging.dll from vsa64 to C:\Program Files (x86)\Common Files\Acronis\BackupAndRecovery\Common64

5) Start all Acronis services
